CVE ID :CVE-2026-49754<\/p>\n
Published : June 2, 2026, 4:16 p.m. | 16\u00a0minutes ago<\/p>\n
Description :Allocation of Resources Without Limits or Throttling vulnerability in elixir-mint Mint allows attacker-controlled HTTP\/2 servers to exhaust memory in a Mint client (HTTP\/2 CONTINUATION flood).<\/p>\n
When Mint’s HTTP\/2 receive path observes a HEADERS frame without the END_HEADERS flag, the unparsed header-block fragment is parked in conn.headers_being_processed, and every subsequent CONTINUATION frame on that stream is appended to the accumulator. Nothing in the receive path caps the accumulator: there is no per-stream size limit, no CONTINUATION frame-count limit, and max_header_list_size is only enforced on outgoing requests, never on inbound header blocks (its default is :infinity).<\/p>\n
A malicious or compromised HTTP\/2 server can stream an endless sequence of CONTINUATION frames (each up to the peer-advertised SETTINGS_MAX_FRAME_SIZE) and drive the client’s iolist to arbitrary size, causing memory exhaustion and BEAM process death. A single connection to an attacker-controlled HTTP\/2 endpoint is sufficient.<\/p>\n
This issue affects mint: from 0.1.0 before 1.9.0.<\/p>\n
Severity: 8.2 | HIGH<\/p>\n
